The Board of Education is putting 1,100 school-safety plans online to help authorities better respond in the event of a Columbine-like disaster and other emergencies, The Post has learned.

With the click of a mouse, the schools chancellor, superintendent, cops and firefighters would get immediate access to basic information about school buildings, including details of all entrances and exits.

The plans also provide room numbers of the principal and other critical offices, and the whereabouts of the gymnasium and auditorium.

The data includes all class schedules, lunch and dismissal times, and the names of employees and students with disabilities, emergency procedures, and what to do if intruders enter the building.

The online program was launched at the behest of Chancellor Harold Levy, who has pushed to modernize the board’s functions.

“We’re in the 21st century. We want to do everything online,” said Deputy Chancellor Burt Sacks.

The information will not be available to the general public. School officials said doing so could jeopardize public safety by providing confidential information to criminals.

Users will need a password to get in.

“If there’s a fire that occurs at night or over the weekend, people will have access to the safety plan,” Sacks said.

Sacks noted that during the Columbine HS massacre in Colorado two years ago, authorities did not immediately have crucial information about the layout of the building, which could have saved students’ lives.

Until now, school officials and the NYPD – who took over school security two years ago – have had to scramble to offices and retrieve files during emergencies.

Sacks said incident reports from the schools also will be put on the board’s Web site in the future.

Up-to-the-minute computerized data would help safety officers and school officials analyze the number of incidents reported at each school, and deploy staff based on those figures to prevent future troubles.

Principals are supposed to e-mail their plans to the board by Oct. 20. Computer problems have slowed the process. A virus shut down the system for two days last week.
